SPECIFICATION forming part of Letters Patent No. 632,381, datedSeptember 5, 1899.

Application filed August 15, 1 898.

To all whom it may concern.-

Be it known that I, PAUL THEADORE, a citizen of the United States,residing at Lansing, in the county of Ingham and State of Michigan, haveinvented certain new and useful Improvements in Vises; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, forming a part of this specification.

This invention relates to vises, and especially that class employed forholding bicycles while they are being operated upon; and it has for itsobject to provide a simple and durable means whereby the article heldwithin said vise may be adjusted to any desired position withoutdisturbing the clamping-jaws.

A further object is to furnish a construction that will enable theoperator to shift the holding-jaws easily and quickly.

The invention consists in the general construction and arrangement ofthe various parts to be hereinafter described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective viewof the device in its assembled form. Fig. 2 is a vertical section of thejaws and horizontal arm. Fig. 3 is a vertical section of the universaljoint which unites the standard and horizontal arm. Fig. 4 is anelevation of one of the clamps, showing the form of the ears. Fig. 5 isan elevation of the disk, showing the lug thereon by means of which thearm is held from dropping.

Like letters of reference refer to corresponding parts throughout thevarious figures.

A represents the standard,'which may be constructed in any suitable formto rest upon the floor. It comprises the base portion a, having thesleeve 19 formed at the top, and a telescoping vertical leg 0, held inthe sleeve by means of the set-screw d.

B represents the universal joint, which unites the standard with thehorizontal arm G and is composed of the clamping-block (2, having theplate f rising from and formed integral with the upper end thereof, asshown in Figs. 3 and at, and the horizontal clampingblock g, upon therear side of which is formed a disk h. These two clamping-blocks areunited, as shown in Fig. 3. The opening i is Serial No. 688,590. (Nomodel.)

formed through the center of the plate fand the short bossj, formedintegral with the disk 7t and adapted to fit within the said opening,-so that it will turn freely therein. The rear end of the boss is halfchecked and receives the plug it, which also engages within the opening71 and is provided with the flange Z to rest against the rear face ofthe plate. There is an opening provided through the plug to receive thebolt m, which is threaded to engage within the boss upon the disk andupon its outer end provided with an ear to receive the cam-lever G. Thehalf-checked portions of the boss and plug which register with eachother compel the parts to rotate together, and as the adjacent faces ofthe disk and plate are furnished with suitable friction material it willbe readily seen that a downward move ment of the cam-lever would causethe two faces to be held firmly together. Thus the horizontal arm, whichis held within the block '9, may be swung to any desired angle in avertical plane and securelylocked in its adjusted position.

In order that the arm may not drop below the horizontal plane, the platef has formed on the opposite edges thereof the shoulders H H, and uponthe disk there is provided the lug I, adapted to rest upon either one orthe other of said shoulders, so that the downward movement upon eitherside will be checked. arrangement furnishes a substantial support forarticles of heavy weight at the outer end of the arm and avoids thepossibility of the accidental droppingof that end while the operator isworking upon the article secured therein.

Referring to Fig. 2, it will be seen that the end of the arm 0 engagedwithin the block g is grooved to receive the end of the small pin Thisor screw 0, so that it may rotate freely, but

is held from longitudinal movement. At the opposite end of this arm thejaws D are carried, consisting of the fixed jaw 15 and the movable jaws. The said movable jaw is formed integral with the sleeve to, whichfits freely over the arm 0, upon which it is guided, and the oppositeend is slightly enlarged to receive the grooved hub 12 of the handwvheelE. The hub of the wheel 'is threaded internally to engage with thethreaded portion 7' of the arm, and as the pin 6, which passes throughthe shell of the sleeve, engages within the groove y a rotation of thehand-wheel will cause it to travel upon the threaded portion of the arm,carrying the sleeve and movable jaw with it. The fixed jaw 25 is securedto the outer end of the arm by means of the pin 1) and remainspermanently adjusted with respect to the arm. As a means of compellingthe movable jaw to operate in the same plane with the fixed jaw Iprovide the perforated extension f upon the movable jaw to receive andmove freely upon the rod 71. and the extension g' upon the fixed jaw,within which one end of said rod is firmly fixed.

The clamping-blocks by means of which the arm is controlled both in itsrotation around the axis of the vertical leg and also upon its own axisare both identical in construction and operation, and it is believedthat the description of one will sufiice.

In Fig. 4: I have shown the block 6 in elevation, and in itsconstruction it is preferably made of a single casting, with the slot inone side thereof. Upon this slotted side and extending therefrom are theears Z n, both of which are inclined upon their outer faces, as shown atn. The lever 19 is constructed in a Y form, so that it will engage uponboth inclined faces of theears, and the inner engaging faces of thelever are also inclined, so that the adjacent surfaces will lie in thesame plane when the clamping-block is in its open condition. By thismeans it will be seen that as the outer end of the lever isdepressedassuming it to occupy an elevated position when the adjacentfaces are in the same plane-the cars will be forced toward each other,causing the slot to be partially closed and firmly clamping the memberwithin the block. The elasticity of the metal permits sufficientspringing action to allow the arm or leg to move freely when the levershave been swung to the proper position, relieving the clamping action,and will readily permit of the binding or clamping force brought to bearthereon by the means above described.

In the operation of my invention assuming that it is desired to secure abicycle within the jaws for the purpose of cleaning or otherwiseoperating upon it that portion of the frame which it is desired tosecure in the vise is placed between the jaws, which are previouslyfitted with Wood bushings to properly embrace the frame, whereupon thehandwheel E is turned until the part is firmly secured. Should it becomenecessary to shift the wheel around the axis of the leg 0, the lever 19is raised, releasing the clampingblock, which turns freely to anydesired position, where it may be secured by drawing the lever down. Toinvert the frame of the bicycle without removing it from the jaws, thelever 10 is raised to relieve the friction contact between the plate anddisk, whereupon the arm may be swung over to the opposite side, where itmay again be fixed by means of the lever. Similar results in theadjustmentaround the axis' of the arm may be accomplished bymanipulating the lever 29 upon the clamping-block g, which is adaptedtosecure the arm in its adjusted position.

From the foregoing it will be obvious that the essential novelty of myinvention lies in the general construction and arrangement of the parts,whereby I am enabled to secure an object within a vise, in which securedcondition it may be shifted or adjusted to any desired position to suitthe convenience of the workman, and although I prefer the particularform herein shown and described I desire to have it understood that someslight modifications may be made without materially affecting theresults or departing from the spirit and scope of my invention.

As the blocks (not shown) which are placed in the jaws to prevent injuryto the parts held therein are apt to drop out when the vise is beingadjusted from side to side, I provide the springs a b in the upper jawsof flat steel, so they will press against the blocks and hold them inposition.

Having thus described my invention, what I claim is- 1. In a vise, thecombination of a standard, comprising a base portion and averticallyadjustable leg, a universal joint mounted upon the outer endof said leg, an arm adjustably secured to said universal joint, jawsmounted upon the outer end of said arm, one of which is fixed and theother movable, and means for manipulating said movable jaw,substantially as described. 0

2. In a vise, the combination of a standard, a clamping-block mountedupon said standard adapted to turn therein, means for securing saidclamping-block, whereby it may be fixed with respect to said standard, asecond clamping-block, adj ustably connected to said first-namedblock,whereby said second clam ping-block may be adjusted at any anglein a vertical plane, means for securing said second clamping-block inits adjusted position, an arm loosely held within said second block,means whereby said arm is permitted to rotate, and is held fromlongitudinal movement within said block, clamping-jaws mounted upon theouter end of said arm, one of which is fixed and the other movabletherein, means for guiding said movable jaw, whereby it is held in thesame horizontal plane with respect to said fixed jaw, a hand-wheelhaving its hub internally threaded to engage a threaded portion of saidarm, and means for uniting the hub of'said wheel and said movable jaw,whereby the rotation of said hand-wheel compels a longitudinal movementof said jaw, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
